Bandar Al-Jaloud, Saudi Royal Palace, AFP | A handout picture provided by the Saudi Royal Palace on November 26 shows Saudi Crown Prince speaking at a meeting of defence ministers and officials in Riyadh.

The newly-built chateau was sold to a mystery buyer in 2015, and though its ownership is concealed through shell companies, advisers to the royal family have confirmed the prince is its ultimate owner, the Times reported Saturday.

Saudi officials have declined to comment on the report, which comes after French investigative website Mediapart similarly pointed to the prince as the owner in July.

Fortune magazine reported at the time of the 2015 sale that the Chateau Louis XIV -- which has fountains that can be controlled by iPhone -- had smashed records to become the world's priciest home.

On the outside, the mansion looks like a 17th-century chateau in the style of the palace at nearby Versailles, but it is in fact a new-build that went up after its Saudi developer bulldozed the existing 19th-century property.

Its antique facades hide modern facilities including a cinema, deluxe swimming pool and a moat with a transparent underwater chamber so that visitors can enjoy the sight of koi carp swimming past.

The 57-acre plot includes manicured gardens, huge fountains and a maze, while the interiors are lavishly decorated with gilding and fresco ceilings.

Corruption crackdown

The Times report comes after the prince had dozens of members of the Saudi elite including princes, ministers and tycoons locked up in Riyadh's 5-star Ritz-Carlton hotel as part of an anti-corruption campaign.
